(Combat)
You've become so adept at combating summoned creatures that you can interrupt the magical energies that summon them to your plane.
Prerequisites
Arcane Strike or
Disruptive,
Banishing Critical,
Combat Reflexes,
Dimensional Awareness,
Spellcraft 8 ranks, arcane pool class feature.
Benefit
When you use
Dimensional Awareness to make an attack of opportunity against a creature being summoned or called into a square you threaten, you can additionally use an
Immediate Action to attempt to send the creature back to its home plane. Attempt a
Spellcraft check (DC = 15 + the creature's CR [minimum 1] + the spell level of the spell that summoned the creature). If you succeed, the creature does not get to act and is immediately sent back to its home plane.
Normal
A summoning or calling spell can be disrupted only by a failed concentration check or by countering the spell.
